Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the initial principal and the accumulated interest from previous periods, helping savings grow faster over time.
What is the compound interest formula?
The formula is A = P * (1 + r/n)^(nt), where A is the future value, P is the principal, r is the annual interest rate, n is the compounding frequency, and t is the tenure in years.
How does compounding frequency impact returns?
More frequent compounding (e.g. monthly or daily) generates slightly higher returns than less frequent compounding (e.g. annually) due to faster interest accumulation.
What is the Rule of 72?
The Rule of 72 is a quick way to estimate when your investment will double. Divide 72 by your annual interest rate to find the approximate number of years needed.
Is my financial data kept secure?
Yes. The calculator runs locally on your device, ensuring your investment details remain private.
Can I use this for Fixed Deposits (FD)?
Yes. Indian bank FDs typically compound quarterly. Select the quarterly compounding option for FD projections.
What is the difference between simple and compound interest?
